<p><font size="2">I believe the WPA IE is only published in a WiFi Alliance specification, but you can indirectly get information about its format from looking at wpa_supplicant&#39;s source or firing up Wireshark and letting the dissectors show you the fields. If your only goal is identification, WPA is a vendor specific IE (decimal 221) and use an OUI of 0x00 0x50 0xF2. Compared this to the RSN IE which has its own IE (decimal 48).<br>

Subject: WPA IE format<br>
<br>
Hi,<br>
<br>
I don&#39;t see format for WPA(TSN) information element in the IEEE 802.11i-2004<br>
draft, though they have mentioned details for WPA2(RSN) information element.<br>
<br>
Is there any documented way on identifying if the AP is WPA or WPA2<br>
compliant, on the basis beacon frame parse results?<br>
<br>
<br>
Thanks<br>
